You Did It!

Wow—thank you to our participants and donors for helping us reach a new Bird-a-thon record.

Because Nature Needs Our Focus

Bird-a-thon, Mass Audubon’s largest fundraiser, brings together supporters from across the state to raise essential funds for nature conservation, education, and advocacy—and to compete in an exciting team birding competition. Each year, more than 800 birders work with their team members to see, hear, and identify as many bird species as possible in a 24-hour period. Team members and other supporters raise money for Mass Audubon sanctuaries and programs in honor of their participation.

Since this fundraiser began in 1983, thousands of dedicated Bird-a-thon supporters and team members have raised well over $3 million for Mass Audubon, its wildlife sanctuaries, and its programs across the state.

Join a Team

Participate in Bird-a-thon by joining a team as an Official Birder or a Bird-a-thon Booster and help raise money for your favorite sanctuary or program! An Official Birder’s species checklist counts towards their team’s total, while Bird-a-thon Boosters bird for fun, do their own nature-bases activity, or participate solely through fundraising.
